CARL ROSENFELD, OF BERLIN, GERMANY.

APPARATUS FOR PRODUCING ILLUSORY EFFECTS.

SPECIFICATION forming part of Letters Patent No. 787,946, dated April 25, 1905.

Application filed September 13, 1904. Serial No. 224,329.

To (HZ when it nut concern;

Be it known that I, CARL RosENEELo, director, of 52 Behren street, Berlin, Germany, have invented certain new and useful improvements in Apparatus for Producing Illusory Effects, of which the following is a full, clear, and exact specification.

My invention relates to apparatus with which in an apparently vacant closed receptacle having glass sides a person can suddenly be made to appear, as it were, magically.

The essential feature of the apparatus is that the glass receptacle is carried by a freelyexposed table, trestle, or other support, into the top of which the receptacle is sunk to such depth that in the chamber or recess concealed by the table-top sufficient room is presented to contain the person who is subsequently to appear in the receptacle.

The apparatus may be perfected by the concealed person lying on a false bottom or partition held down against the action of strong springs by means of a catch or like device, on the release of which the false bottom ascends to the same level as that of the surface or top edge of the table or other support.

A further perfection consists in the chamber above the person being covered by a double door or bya sheet or cloth, presenting the appearance of a bottom, and normally kept in closed or taut condition by or against the action of springs, but on release of the latter opening or rolling up automatically in the manner of a window-blind.

The person reclining on the bottom of the receptacleis supplied with air in suitable manner, preferably by means of a mouthpiece and a flexible tube conducted through a hollow corner-pillar of the receptacle.

The accompanying drawings show one form of construction of the new apparatus.

Figure l is a side elevation; Fig. 2, a longitudinal section, and Fig. 3 a cross-section. Fig. 4 is a sectional plan view.

6 is a glass-sided receptacle which is filled with water and has the appearance of standing on the table 1), though in reality let into the top of the latter.

is a false bottom or partition resting on spiral springs f.

a is a catch which holds the rising bottom in its lowermost depressed position, with the springs f compressed.

(Z is a sheet or cover stretched across the receptacle and held taut by means of a rod 0, having suitable eyes or loops, against the action of rubber cords or the like.

0 is a raised portion of the table-top concealed by a molding and rising to the level of the stretched cover (I, which latter thus presents the appearance of being the actual bottom of the receptacle I). The person who is subsequently to apparently magically appear lies in the recess of the table upon the false or rising bottomz below the cover (I. One of the pillars h of the receptacle may be hollow to receive a rubber pipe 7 or the like, with a mouthpiece for the purpose of supplying the concealed person with air.

On exhibiting, the catch a is withdrawn, so as to set free the partition and the catch holding the cover (Z stretched likewise released. Hereupon the partition will rise, together with the person reclining thereon, who through the simultaneous withdrawal of the cover (Z is exposed and can now rise from the water.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An apparatus for producing illusory effects, comprising a support, a transparent water-receptacle let into the support, a springactuated rising bottom located in the receptacle, and means for normally holding the said spring-actuated bottom in depressed position, substantially as described.

9.. An apparatus for producing illusory effects comprising a support, a transparent wator-receptacle let into the support, a springcontrolled cover located at the level of the top of the support, substantially as described.

3. An apparatus for producing illusory cffects, comprising a support, a transparent Wathe said pillar to the bottom of the receptacle, I0 ter-receptacle let into the support, a springsubstantially as described.
